Open Stack

Hi,

really interesting, thanks corry.
during l3 meeting we spoke about planning a POD session around bgp use cases.
at least 2 spec have bgp use cases :

https://review.openstack.org/#/c/125401/
https://review.openstack.org/#/c/93329/

It would be interesting that you join this POD, to share your view and
leverage bgp capabilities that will be introduced in kilo for the
calico project.
